Description

Technical Field

[0001] This application relates to the field of water level monitoring technology, and more specifically, to a watershed water level monitoring device. Background Technology

[0002] Research on wetland environmental elements mainly involves hydrological measurements, such as water level, flow rate, flow velocity, rainfall (snow), evaporation, sediment, ice formation, soil moisture, and water quality. Among related technologies, radar level gauges are commonly used for water level measurement. Radar level gauges are electronic devices that use electromagnetic waves to detect targets. They are characterized by low energy consumption, high accuracy, and high stability. Measurements are unaffected by atmospheric temperature, pressure, air density, wind, precipitation, and relative humidity, exhibiting extremely high stability. They are suitable for field environments such as lakes, rivers, reservoirs, open channels, and wetlands, and are therefore widely used in water level measurement activities.

[0003] Currently, radar level gauges are generally installed above the water surface using fixed brackets, making it difficult to extend, retract, or adjust their height. Therefore, when used in harsh environments such as canyons, valleys, or open channels with unique terrain, it is often difficult to find a suitable location to install the bracket. The bottom of rivers, valleys, or canals is also prone to rockfalls and exposure due to changes in flow, which can make it difficult to adjust the radar level gauge to its position above the water surface, causing it to deviate from the water surface and resulting in significant measurement errors.

[0045] Example

[0046] like Figures 1-9As shown, the water level monitoring device according to an embodiment of this application includes a radar level gauge body 100, a moving adjustment mechanism 200, a lifting mechanism 300, and a center of gravity adjustment mechanism 400. The radar level gauge body 100 is disposed below the moving adjustment mechanism 200 to facilitate adjustment of its position above the water surface. The lifting mechanism 300 is disposed between the radar level gauge body 100 and the moving adjustment mechanism 200 to facilitate adjustment of the height of the radar level gauge body 100. The center of gravity adjustment mechanism 400 is disposed on the moving adjustment mechanism 200 to facilitate maintaining the stability of the entire monitoring device when the height of the radar level gauge body 100 changes.

[0047] According to some embodiments of this application, such as Figure 3 As shown, a number of first counterweights 110 are arranged around the radar level gauge body 100. The first counterweights 110 are evenly distributed and can keep the radar level gauge body 100 in a vertical state.

[0048] According to some embodiments of this application, such as Figures 2-5As shown, the movable adjustment mechanism 200 includes a cableway 210, a first housing 220, a battery 230, rollers 240, a servo motor 250, and an axle 260. The radar level gauge body 100 is located below the first housing 220. Two cableways 210 are arranged side by side. Two rollers 240 are respectively located at both ends of the axle 260. Both ends of the axle 260 are fixedly inserted through the rollers 240. The two axles 260 are arranged side by side, and the rollers 240 are mounted on the cableways 210. Both ends of the axle 260 are rotatably connected to the inside sides of the first housing 220. Through slots 222 are respectively opened at the four corners of the first housing 220. A second housing 223 is provided on one side of the first housing 220. A servo motor 250 is located inside the second housing 223. A battery 230 is located inside the first housing 220 on the side away from the second housing 223. The battery 230 and the servo motor 250 are electrically connected. The servo motor 250 is driven by an axle 260. A solar panel 221 is provided on the top side of the first housing 220. The solar panel 221 and the battery 230 are electrically connected. Hooks 211 are provided at both ends of the cableway 210. The middle of the hook 211 rotates through one end of the cableway 210. The hooks 211 facilitate the installation and maintenance of the cableway. A fixed cableway 210 is provided, with a plurality of slots 212 evenly distributed. A roller 240 has a plurality of protrusions 242 evenly distributed around its periphery, with the protrusions 242 corresponding to the slots 212. The cooperation between the protrusions 242 and the slots 212 prevents the roller 240 from slipping. A limiting wheel 241 is provided below the roller 240, with its periphery fitting against the lower side of the cableway 210. The limiting wheel 241 is connected to an axle 260 via a first connecting plate 262, and is rotatably connected to the lower end of the first connecting plate 262. The axle 260 rotatably passes through the first connecting plate 262. At the end, the limiting wheel 241 can further limit the roller 240, making it more stable and smooth to drive the entire monitoring device to move on the cableway 210, thereby smoothly adjusting the position of the radar water level gauge body 100 above the water surface. The output end of the servo motor 250 is equipped with a first bevel gear 251, and a second bevel gear 261 is provided on the axle 260. The axle 260 is fixedly inserted through the second bevel gear 261. The first bevel gear 251 and the second bevel gear 261 mesh. The servo motor 250 can provide power to the entire monitoring device smoothly through the meshing of the first bevel gear 251 and the second bevel gear 261.

[0049] According to some embodiments of this application, such as Figures 2-3 , Figures 6-7As shown, when the water level changes due to different flow rates, the radar level gauge is prone to measurement blind spots, leading to significant measurement errors. Furthermore, the radar level gauge requires certain protection; without effective protection, its lifespan will be affected by factors such as sunlight and rain. The lifting mechanism 300 includes an electric push rod 310, a universal joint 320, a first support rod 330, a first connecting rod 340, a first connecting block 350, and a first protective cloth 360. The upper end of the electric push rod 310 is fixedly connected to the first housing 22. Inside the top center of the 0, an electric push rod 310 is positioned between two cableways 210. A second connecting plate 311 is located at the lower end of the piston rod of the electric push rod 310. A universal joint 320 is positioned below the second connecting plate 311. The radar level gauge body 100 is positioned below the universal joint 320. Several first support rods 330 are evenly arranged around the second connecting plate 311. The upper ends of the first support rods 330 are rotatably connected to the edge of the second connecting plate 311. A first connecting block 350 is positioned on the sleeve of the electric push rod 310. A connecting rod 331 is provided on the upper side. The lower end of the first connecting rod 340 is rotatably connected to the upper end of the connecting rod 331. The upper end of the first connecting rod 340 is rotatably connected to the outside of the first connecting block 350. The upper edge of the first protective cloth 360 is fixedly connected to the lower edge of the second connecting plate 311. The four lower corners of the first protective cloth 360 are fixedly connected to the lower end of the first support rod 330. The first counterweight 110, in conjunction with the universal joint 320, can keep the radar level gauge body 100 vertical, improving measurement accuracy. When it is necessary to adjust the radar level gauge body 100... When the height is adjusted by the electric push rod 310, after the radar level gauge body 100 drops to a certain height, the first connecting block 350 will pull the first support rod 330, and the first support rod 330 will be opened by the connecting rod 331, thereby opening the first protective cloth 360. After the radar level gauge body 100 is lowered and away from the first housing 220, the radar level gauge body 100 is effectively protected, avoiding the influence of sunlight, rain and other factors on the accuracy of water level measurement of the radar level gauge body 100, and effectively extending its service life.

[0050] The second connecting plate 311 has several first abutments 3111 evenly arranged on its upper side and several second abutments 3112 evenly arranged on its lower side. The first abutments 3111, the second abutments 3112 and the first support rod 330 are correspondingly arranged. The first abutments 3111 and the second abutments 3112 can provide effective limiting for the first support rod 330. Several first elastic bands 332 are arranged between the lower ends of the several first support rods 330. The lower edge of the first protective cloth 360 is fixedly connected to the first elastic band 332. The first protective cloth 360 can generally be made of a material with a certain degree of elasticity to facilitate opening and closing. The first elastic bands 332 are beneficial to effectively stretch the first protective cloth 360 after the first support rod 330 is opened.

[0051] According to some embodiments of this application, such as Figures 2-3 , Figure 6 and Figures 8-9As shown, when the electric push rod 310 adjusts the height of the radar level gauge body 100, the overall center of gravity of the entire monitoring device will change. When the height of the radar level gauge body 100 decreases, the center of gravity of the entire device will shift downward, which helps maintain the stability of the entire monitoring device. However, when the height of the radar level gauge body 100 increases, the center of gravity of the entire device will shift upward, causing the overall structure of the monitoring device to become unstable and making it difficult to effectively counteract the influence of wind. This will make it difficult for the radar level gauge body 100 to work stably, thus affecting the accuracy of the measurement results. The center of gravity adjustment mechanism 400 includes a second connecting block 410, a second connecting rod 420, a slide rail 430, a slider 440, a third connecting rod 450, a second counterweight 460, and a second protective cloth 47. 0. The sleeve of the electric push rod 310 slides through the second connecting block 410. Two limiting rings 412 are provided on the sleeve of the electric push rod 310. The two limiting rings 412 are respectively located above and below the second connecting block 410. Springs 411 are respectively provided between the two limiting rings 412 and the second connecting block 410. The two ends of the springs 411 are fixedly connected to the limiting rings 412 and the second connecting block 410. The first connecting block 350 is slidably connected to the slider 440. Several slide rails 430 are evenly distributed around the upper end of the electric push rod 310. The slide rails 430 are fixedly connected to the top side inside the first housing 220. The slider 440 is slidably connected to the slide rails 430. The lower end of the second connecting rod 420 is rotatably connected to the outside of the second connecting block 410. On one side, the upper end of the second connecting rod 420 is rotatably connected to the slider 440, and the upper end of the third connecting rod 450 is rotatably connected to the slider 440. The second connecting rod 420, the third connecting rod 450, and the through groove 222 are correspondingly arranged. The upper end of the second connecting rod 420 is drivenly connected to the upper end of the third connecting rod 450. The second counterweight 460 is fixedly connected to the lower end of the third connecting rod 450. A second support rod 451 is arranged on the upper side of the third connecting rod 450. The upper edge of the second protective cloth 470 is fixedly connected to the upper edge of the first housing 220. The four corners of the lower side of the second protective cloth 470 are fixedly connected to the upper end of the second support rod 451. The slider 440 is equipped with a first incomplete gear 421 and a second incomplete gear 453. The first incomplete gear 421 and the second incomplete gear 453 are arranged inside the slider 440. 53 is rotatably connected to slider 440. The first incomplete gear 421 and the second incomplete gear 453 mesh. The upper end of the second connecting rod 420 is fixedly connected to one side of the first incomplete gear 421, and the upper end of the third connecting rod 450 is fixedly connected to one side of the second incomplete gear 453. When the height of the radar level gauge body 100 drops to a certain level, the upper side of the first connecting block 350 abuts against the upper side of the second connecting block 410. After the first protective cloth 360 is opened, if the radar level gauge body 100 continues to descend, the upper side of the first connecting block 350 will press the second connecting block 410 down together. The second connecting rod 420 will pull slider 440, and the second connecting rod 420 will drive the first incomplete gear 421 to rotate and drive the second incomplete gear 453.This causes the third connecting rod 450 and the second counterweight 460 to retract towards the first housing 220, lowering the center of gravity of the entire monitoring device structure. Conversely, when the radar level gauge body 100 rises, after the first protective cloth 360 is retracted, the lower side of the first connecting block 350, after contacting the lower side of the second connecting block 410, will continue to push it upwards. The second connecting rod 420 drives the first incomplete gear 421 to rotate, driving the second incomplete gear 453. This causes the third connecting rod 450 and the second counterweight 460 to open away from the first housing 220, raising the center of gravity of the entire monitoring device structure. This maintains the stability of the overall structure, effectively counteracts the influence of wind, and makes the radar level gauge body 100 work more stably, improving the accuracy of water level measurement.

[0052] Among them, several second elastic bands 452 are provided between the upper ends of several second support rods 451, and the lower edge of the second protective cloth 470 is fixedly connected to the second elastic bands 452. The second protective cloth 470 is generally made of a material with a certain elasticity so as to facilitate opening and closing. The second elastic bands 452 are conducive to tightening the second protective cloth 470.

[0053] Specifically, the working principle of this watershed water level monitoring device is as follows: During use, suitable fastening devices, such as anchor bolts or foundation piles, are installed on the slopes or cliffs of the canyons, gullies, or canals where water level measurements are required. Two cableways 210 are suspended as horizontally as possible above the water surface via hooks 211. The monitoring device is then placed on the cableways 210. A servo motor 250 drives a wheel axle 260, causing the first housing 220 to move the radar water level gauge body 100 along the cableways 210. The first counterweight 110, in conjunction with the universal joint 320, keeps the radar water level gauge body 100 vertical, improving measurement accuracy. The convex strip 242 and the slot 212 prevent the roller 240 from slipping, and the limiting wheel 241 further supports the roller. Limiting the movement of the radar level gauge 100 on cableway 210 ensures a smoother and more stable movement of the entire monitoring device. This allows for a stable adjustment of the radar level gauge 100's position above the water surface, enabling adjustments based on actual water conditions. When the height of the radar level gauge 100 needs adjustment, it is done via electric push rod 310. Once the radar level gauge 100 has descended to a certain height, the first connecting block 350 pulls the first support rod 330, which in turn opens via connecting rod 331, thus expanding the first protective cloth 360. This effectively protects the radar level gauge 100 from sunlight after it has lowered its height and moved away from the first housing 220. Rain and other factors can affect the accuracy of water level measurement of the radar water level gauge body 100 and effectively extend its service life. When the height of the radar water level gauge body 100 drops to a certain level, the upper side of the first connecting block 350 abuts against the upper side of the second connecting block 410. After the first protective cloth 360 is opened, if the radar water level gauge body 100 continues to drop, the upper side of the first connecting block 350 will press the second connecting block 410 to move down together. The second connecting rod 420 will pull the slider 440. The second connecting rod 420 drives the first incomplete gear 421 to rotate and drive the second incomplete gear 453, thereby causing the third connecting rod 450 and the second counterweight 460 to retract towards the first housing 220, completing the downward shift of the center of gravity of the entire monitoring device structure. Conversely, when the height of the radar water level gauge body 100 increases, the radar water level gauge body 100 will continue to drop. As the temperature rises, after the first protective cloth 360 is retracted, the lower side of the first connecting block 350, after contacting the lower side of the second connecting block 410, will continue to push it upward. The second connecting rod 420 drives the first incomplete gear 421 to rotate, driving the second incomplete gear 453, thereby causing the third connecting rod 450 and the second counterweight 460 to move away from the first housing 220 and open up, completing the upward shift of the center of gravity of the entire monitoring device structure, thus maintaining the stability of the overall structure, effectively offsetting the influence of wind, making the radar level gauge body 100 work more stably, and improving the accuracy of water level measurement. In this way, the position and height of the radar level gauge body 100 above the water surface can be freely adjusted, avoiding large measurement errors caused by the radar level gauge body 100 deviating from the water surface or the generation of measurement blind spots.

[0054] It should be noted that the specific models and specifications of the radar level gauge body 100, solar panel 221, battery 230, servo motor 250 and electric push rod 310 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0055] The power supply and operating principle of the radar level gauge body 100, servo motor 250 and electric push rod 310 are clear to those skilled in the art and will not be described in detail here.

[0056] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
